,A further object of the invention is the provision of a wind mill constructed in such be tilted in such manner that the blades will present a much reduced area to the action of the wind.

Further objects andadvantages of the invention will be set forth in the detailed description which now follows.

In the accompanying drawings: Figure'l is a side elevatlon-of a Wind driven pump wheel, Fi 3 is a vertical section through a portion 0 the wind mill, and, Fig. '4 is a detail sectional view of a connection between rod and a disk hereinafter described.

Like. numerals designate corresponding parts in all of the figures of the drawing.

- Referring o the drawing, the numeral 5- desi nates a tower, which may be of any derovided with a. p atform 6.: A' sleeve 7 w ich is'carried by aswinging table rudder vane 9,. Mounted 1n [bearings 10 vents endwise movement of saidishaft in one,

direction, while a pinion '13 alsd'secured upon pump 16,-the parts so far described being of the usual and well known construction;

Adischarge pipe 17 leads from the pump 16 and is adapted to discharge into a tank 18. Radial arms 19 are secured to the shaft-ll by means of bolts 20 and plates 21,] the bolts 20' the shaft 11. .Pivoted between these radial arms upon bolts 23 are triangular. frames 24,

' serving to clam theradial arms 19 between the plates, as Wlll be readily understo'od. A- -key 22 causes these radial arms to turn with these triangular frames carrying the blades or vanes 25 of the wind wheel @onnected to the inner ends of these triangular frames are links 26, said links being in turn con- 170i nected to pins 27 .which are carried by a plate 28.- This plate is, normally forced away from the bodyof the windwheel by'a I spiral spring 29 whiclrbears between said plate and the wind wheel. A disk 30 lies etween the plate 28 and a pin 3'1,said pin 1 being slidably disposed in" a slot 32 of the ing-between disks 33 which are secured by nuts 34 (see Fig. 4) u on a rod 35, said rod passin through the ollow shaft 11';

shaft 11 and the inner end of said pin enter- The- end 0 this rod is connected to a flexiblememberf36, such as a cord, said flexlble member passing through a pulley 37 which.

is carried by the rudder vane 9, then over a pulley 38 which is carried by the swinging, table 8, through the sleeve 7, over pu1leys39 'and 40 and is secured at its lower end'to a ail'or' bucket 41. An overflow pipe 42 om. the tank, overliesthis pail and sad ail is provided with a very small outletor ip' opening 43.. r 1

The operation of the device is as follows: When the wind is of ordinary velocity, the triangularframes are held in a substantially vertical .osition by the spring 29 outward yu on the plate 28 and since the ro s 26 connect the plate 28with these .triangularframes. At this time the blades or vanes 25, presenttheir mostefiect ive working surfaces to the wind and the wheel is caused to revolve and to pump water to the tank 18 through the'connections-described. If, however, the wind reaches". an excessive velocity, its pressure upon the disk-'30 against the tension of the spring 29. This rocks th e.trian]fiular frames-24 to the dotted line/positions ustrated in Fig. ,3 and ceng.

inc

I move said disk and consequently the late 28 to the right in Fig. 3, this movement eing sequently moves the blades to such an angle that they no longer present an efiective working surface to the wind and thewheel is brought to a standstill, or if it revolves at'all, its revolution will be very slow. As to whether it shall be permitted to revolve at all, may be readily determined by the tension or resistance of the spring 29.; If, how- 1 ever, the wind remains at ordinary working velocity and the tank 18 be filled, the water through the overflow pipe 42 will fill the pail 41,- whereupon theweight ofsaid ail will to astand-still. -As the Water is used from through the flexible connection '36, raw the ,rod'35 to'the rightin Fig. 3 and tilt the triangular frames to such position asto bring the wind-wheel and consequently the pump the tank 18 and water ceases to fio'w through 'jects of the invention, but W the overflow. pi e42 to the ail 41, saidail will be gradua y emptied through thefiri opening 43. When thispail has been su ficiently emptied, the spring 29 will throw i the plate 28 to the left in Fig; 3 and will conshown and described are Well adapted to serve' the purposes for which they are intended, it is to be understood that the invention is not'limited to the precise-construction Set forth, but includes Within its urview; such changes as may be'made wit in the scope of the appended claims.

upon the rudder vane, 'a second resent i What I claim, is: v

In a device of the character described, the

combination with a supporting tower,- of a swin ing platform mounted'up'on said tower, a hol ow shaft rotatably mounted upon said platform, a plurality'of radial arms secured to'said hollow shaft, a tilt'in frame located between each pair of said ra ial arms, a plurality ofvanes fixedly secured to said tilting frames, a-wind disk slidably mountediupon; the hollow shaft, connections between said wind disk-and said vanes, a spring which normally forces said disk into such position as to hold the vanes into the wind, a rudder vane carried by said swinging platform, a

pump, driving connections bet Qen said pump and the hollow shaft, a rod which passes through the hollow shaft and is con-,

nected to the wind disk, a pulley mounted pulley mounted adjacent the central ort-ion of the swinging platform, a flexib e connection which is connected to the rod and passes first v over the pulley of the rudder vane, then over the pulley that is mounted upon the 'tilt-*.

ing platform and then passes downwardly,

through said tower, a rece taclesecured to- '65 the lower end of' the flexlb e member, a re- Geptacle into which the pump is adapted to Q discharge, and an overflow pipe leading from in presence of two witnesses.-
